I bought this during the special review event and I'm glad I did. First of all it comes in a glass dropper bottle with minimalist design and feels very luxe. 50ml is a generous amount and great value for money. The ampoule is very light and watery, almost similar to a toner or essence and it's fragrance-free. It absorbs quickly into my skin and I could use up to 3 layers without noticing any stickiness. Just 4 drops is enough to cover my face and neck in a single layer and I could do over 2 layers with one full dropper. This ampoule is simple, clean and effective and left my skin feeling well-hydrated. Also the fact that it contains only 1 ingredient, 100% Madagascar Centella asiatica means that your skin is not exposed to any harmful ingredients. If you have oily or sensitive skin you will definitely love this as the texture is so light and gentle. I think this would also be a great starter ampoule for teenagers or someone just getting into k-beauty. I would definitely recommend it!
